J2 haplogroup

It is believed to have evolved in Western Asia.

Suprahaplogroup F is believed to have migrated from Africa approximately 50kya. Haplogroup J arose approximately 30kya see Figure 4 and has been defined by a number of unique Y-chromosome polymorphisms; the 12f2a deletion and the M and P SNPs. Societies, dynasties and empires in this broad region include the Sumerian, Assyrian, Babylonian, Egyptian, Phoenician and Persian. Haplogroup J is also particularly abundant in Anatolia present day Turkey and the Y-chromosome diversity observed here suggests that this area is a possible source of this clade. This spread contributes significantly to populations in European and African countries around the Mediterranean Sea. Moreover, this migration, also termed a "demic diffusion", is believed to be the source of new agriculture practices, which included domestication of animals or pastoralism. It is also associated with sedentism or the custom of living in one place as opposed to the more mobile hunter-gatherer and nomadic lifestyle.

J2 haplogroup

Author: Maciamo Hay. Last update April famous people. Haplogroup J2 is thought to have appeared somewhere in the Middle East towards the end of the last glaciation, between 15, and 22, years ago. This confirms that haplogroup J2 was already found around the Caucasus and the southern Caspian region during the Mesolithic period. The first appearance of J2 during the Neolithic came in the form of a 10, year-old J2b sample from Tepe Abdul Hosein in north-western Iran in what was then the Pre-Pottery Neolithic Broushaki et al. Notwithstanding its strong presence in West Asia today, haplogroup J2 does not seem to have been one of the principal lineages associated with the rise and diffusion of cereal farming from the Fertile Crescent and Anatolia to Europe. It is likely that J2 men had settled over most of Anatolia, the South Caucasus and Iran by the end of the Last Glaciation 12, years ago. Mathieson et al. Lazaridis et al. Likewise, over Y-DNA samples have been tested from Neolithic Europe, covering most of the important cultures, and only two J2 sample was found, in the Sopot and Proto-Lengyel cultures in Hungary, dating from 7, years ago. No Neolithic sample from Central or South Asia has been tested to date, but the present geographic distribution of haplogroup J2 suggests that it could initially have dispersed during the Neolithic from the Zagros mountains and northern Mesopotamia across the Iranian plateau to South Asia and Central Asia, and across the Caucasus to Russia Volga-Ural.

According to the genetic study in Northwest China by Shou et al. J2b2 is also found in Nepal, but no J2b2 has been found in Tibet, providing strong evidence that the Northern spread of this subclade was prevented by the Himalaya Mountains, j2 haplogroup. For a refresher on shiny basculin options for obtaining your Y-haplogroup, review our handy j2 haplogroup in the previous post about haplogroup testing.

The date of origin for haplogroup J-M was estimated by Batini et al in as between 19, and 24, years before present BP. E approximately 11, ybp. It is likely that J2 men had settled over most of Anatolia, the South Caucasus and the Zagros mountains by the end of the Last Glaciation 12, years ago. Zalloua and Wells and al-Zaheri claimed to have uncovered the earliest known migration of J2, expanded possibly from Anatolia and the Caucasus. Per research by Di Giacomo , J-M haplogroup spread into Southern Europe from either the Levant or Anatolia , likely parallel to the development of agriculture.

In order to improve the phylogeography of the male-specific genetic traces of Greek and Phoenician colonizations on the Northern coasts of the Mediterranean, we performed a geographically structured sampling of seven subclades of haplogroup J in Turkey, Greece and Italy. We resequenced 4. We did not find a preferential coalescence of Turkish samples to ancestral nodes, contradicting the simplistic idea of a dispersal and radiation of Hg J as a whole from the Middle East. Upon calibration with an ancient Hg J chromosome, we confirmed that signs of Holocenic Hg J radiations are subtle and date mainly to the Bronze Age. We pinpointed seven variants which could potentially unveil star clusters of sequences, indicative of local expansions.

There is a distinct association of ancient J2 civilisations with bull worship. Mathieson et al. Toggle limited content width. His father was of Romanian Jewish ancestry. The American Journal of Human Genetics. Send Cancel. Tools Tools. Bull-masked terracotta figurines and bull-horned stone altars have been found in Cyprus dating back as far as the Neolithic, the first presumed expansion of J2 from West Asia. Thanseem, I. There is a wide variety of J2a branches found in South Asia. Anyone you share the following link with will be able to read this content:. M Little information is currently known for the J2a4b1a subclade, but it appears to a minor and infrequent subclade. Retrieved August 6, We have also filtered out some highly deviating haplotype samples from any age estimation analyses. Asur, Chenchu , pastorals eg.

Author: Maciamo Hay. Last update July Haplogroup J is relatively evenly distributed across all Europe.

Basu, A. Regueiro, M. The attraction of the fertile Mesopotamian valley may have favored the migration from Anatolia in the West, thus producing a general West to East migration pattern and spread of J2 into Iran. Download as PDF Printable version. MJ median joining tree Fig. Most of the extant mtDNA boundaries in south and southwest Asia were likely shaped during the initial settlement of Eurasia by anatomically modern humans. Archived from the original PDF on 31 January This, combined to the fact that they speak a language descended from Latin, suggests that they could have a greater part of Roman or at least Italian ancestry than other ethnic groups in the Balkans. Archived from the original PDF on 27 December Through a founding effect, J2b2-L lineages might have considerably increased their original frequency after reaching Illyria. Contrary to the widely accepted elite dominance model, we found a substantial presence of J2a-M and J2b-M haplogroups in both caste and tribal populations of India. J-P, and Jf2. A second expansion would have occured with the advent of metallurgy. The table below brings together all of these works at the point of the landmark YCC Tree. It also has a moderate occurrence in Southern Europe , especially in central and southern Italy, Malta, Greece and Albania.
